i know there is a lot to upgrade, but what is the important part to upgrade first...
i also know that longer barrel gives you more power and distance....
that would fit a TM 4.3? would barrels meant for 5.1 can be fitted in a 4.3 or do i need to stick with PDI barrel for 4.3 ....
thank you for your attention to this matter and your advice would be highly appreciated...
btw, i reside in M'sia

I believe you can stick a longer barrel through the 4.3 outer barrel but without a silencer or something of that sort to cover it you'll have the inner barrel sticking out of the gun.
For power; a nice upgrade is the Nineball bucking. The internal lips in the bucking prevent gas from being pushed backwards from the hop bucking (I think? Conventional thinking seem to point to that as a explanation for the fps increase but I'm always weary that to have the gas coming out of the nozzle be reversed in it's vector by 180 degrees seem wrong.) and with +0.25g bbs and the hop up setting nicely done the bucking material will give you a nice backspin. The King Arms one work better than the Nineball I believe but it's made of the same material as pencil erasers and as such I've read that they wear down after 1k rounds on high powered VSRs.
For distance and accuracy; I think many here recommend the Tanio Koba Twist. I think Brian said that with the twist barrel + marui bucking; when he sets the hop up to max it generates the farthest distance the bb can fly with a flat trajectory. I tried it myself and although I don't have enough range to see the effects of the hop up wear off I saw it shoot with a straight trajectory to 40 meters with KSC 0.25g bbs. However the bore diameter is larger than most so you'll see an FPS drop off.
For distance + power, the PDI 6.01 tightbores are favoured in general. Brian said that he noticed the 6.01 barrels are more accurate than the 6.03 nineball make but from the knowledge I gathered elsewhere a tighter bore is actually detrimental to accuracy. However, I also believe that bore consistency weighs more than the bore diameter and given that both Laylax (nineball) and PDI have some of the best bore consistencies at the ranges pistols can hit it may be that there is no noticeable accuracy differences. With that in mind you might prefer the PDI barrels more than the nineball or TK twist.
Use good bbs will also help with accuracy. I think the Excel bbs have a smaller diameter (told to me by a Redwolf employee at a game I was in) so for accuracy they might work better than say KSCs or TMs at longer ranges. Excels are pricier than KSCs or TMs but they are considered to be very well made bbs. Since you won't be shooting a ton of bbs from a pistol compared to an AEG (perhaps I'm wrong? :P) I believe the higher price of the Excels are worth it.
Wait till others on this thread chip in before making your decision though; I typed the above on the go so I dunno if there's anything wrong or debatable in it. More information is better anyway
